According to the British on-line version of “Daily Mail ” news on the September 11th that NASA plans to provide the International Space Station astronauts with the edible vegetables grown in space before the end of the year , the plant cultivation of the space program expects to firstly cultivate six batches of lettuce ，which the pink LED lights will provide with light for photosynthesis .
This is a a dream that since the beginning of human has mastered the space technology, whether you call it ” Space Farms ” or “cosmic agricultural base” , and now will become a reality .
Foreign media reports that NASA will begin trying to grow vegetables in the satellite orbit on December. The first batch of vegetables will be six ordinary lettuce, the pink LED light will be used as light source , which is expected to grow the extent that can harvest within a month .
After experimenting, NASA convinced that zero-gravity environment does not affect the growth of vegetables . But another problem is that micro-organisms of the universe that may arise is not yet resolved during the growth, so these lettuce will undergo the comprehensive inspection before being eaten by astronauts. If the results of this experiment are all normal , then the scale of this experiment will be expanded to provide the space station with long-term food supply. This is the first step towards the establishment of self-sufficient in space station , but also save shipping costs for NASA by the way – in accordance with the current technical conditions , transporting 500 grams of food to the space station costs about $ 10,000 .
Ingredients grown in space will be a good solution to the future long-distance space travel that is a major problem : the supply of fresh food . And in the short term , it can play the role of cost-cutting – the current per 1 kg of food delivery to the ISS spend nearly £ 14,000 , but also are some of the main food high in calories and long-term storage, especially fresh food such as fruits and vegetables is very limited, which will be swept away by the poor astronauts as soon as shipped.
Now a system called vegetable production (VEGGIE) program will start within the next three months . The grown period of the lettuce is very short , once planted , will be able to mature enough to be eaten 28 days later. NASA experiments have previously provable that zero gravity environment does not affect the growth of these vegetables . But there is still a problem to be solved is that the growth process may be bacterial contamination – produce some cosmic microorganisms. So the first batch of lettuce before being eaten by the astronauts will undergo a rigorous and comprehensive examination . If the first round of test results is all normal , VEGGIE plan could expand the scale of the international space station to get a long-term food supply. This is the first step towards the establishment of a ” self station ” . Meanwhile , VEGGIE also provide the astronauts with some of the so-called ” horticultural therapy” to relieve physical and mental stress, relieve depression .
In fact，the crops cultivated in orbit isn’t as the simple as the greenhouse equipment moved to warehouse space. Fortunately, NASA has a long history of cultivation in space , but which are for scientific research and experimental purposes in the past , for example the test that the plant is growth under zero gravity had never designed for people to eat , in accordance with regulations , the astronauts can not eat those ” experimental data .”
The VEGGIE plan is that the NASA firstly attempt to cultivate the food crops to supply astronauts in space . After the ” Space Farms ” dream come true , NASA’s food delivery costs will not only be substantially reduced over the next 10 to 15 years , the humans but also can enjoy a steady stream of fresh ingredients during the great but the long journey to Mars .
Definitely，what we can also see that NASA has showed great interested in LED lighting that is environmentally friendly ，apparently, LED lighting has been completely related to the aerospace technology，moreover is connecting to the design, agriculture, medicine, science and technology and other industry to bring our unique visual experience and convenience.
Meanwhike，the LED flood light such as the portable LED flood light 30W and LED tube light are the most widely used as the representatives of the decorative lighting and the home lighting in daily life，the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile，there a large number of factory engaging in developing and producing the LED light，Lead Lighting is just one of them，which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light so that fully guaranteed stable and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection.
